AI Technical Summary
In existing railway freight inspection equipment, the line scan camera and the light source are directly mounted on the gantry, which makes it difficult to ensure that they are on the same horizontal straight line. This results in poor matching between the light source and the line scan camera, making it impossible to adjust the angle of the light source and affecting the image acquisition effect.
Design an auxiliary mounting bracket, including a fixed bracket and a camera bracket. The light source is mounted on the second mounting surface of the fixed bracket, and the line scan camera is fixed on the second mounting surface through the camera bracket. This ensures that the optical axis of the light source and the camera are in the same vertical plane, and the angle of the line scan camera can be adjusted by adjusting the gap to improve the matching degree.
It achieves optimal coordination between the light source and the line scan camera, eliminates brightness gradients, enhances image detail contrast, and improves the adjustment effect and matching accuracy of the line scan camera.

[0002] With the continuous acceleration of railway transportation, the quality and safety of transportation have become increasingly important. How to speed up vehicle turnaround and freight inspection operations are crucial links in ensuring the safety of railway freight transportation.
[0003] Intelligent inspection equipment for railway freight has been developed. It uses line scan cameras mounted on a gantry to capture images of freight trains, ensuring the reliability of the entire intelligent inspection equipment. The line scan cameras are equipped with light sources to ensure that the image acquisition unit can still operate efficiently even in dim environments.
[0004] However, the existing line scan cameras and light sources used for supplementary lighting on the cargo inspection equipment are directly mounted on the gantry, making it difficult to ensure that they are on the same horizontal straight line to achieve the best supplementary lighting effect of the light source on the line scan camera. In addition, the line scan camera is generally directly fixed on the gantry, making it impossible to adjust the angle of the light source of the line scan camera, resulting in poor matching between the line scan camera and the light source and inconvenience for adjustment.
